Design and Validation of an Instrument for Technical Performance Indicators of the Kick (Chagi) Technique in Taekwondo

Abstract

Taekwondo is a martial art and combat sport that originated in medieval or similar cultures, but today it is primarily a combat activity conditioned by safety rules. The kick technique is called “chagi” (Korean language). “Eyeballing” is a problem that is being addressed with traditional training methods used in Taekwondo. (1) Background: To solve this problem, the main aim of this study was to develop an Observation System for Technical Performance Indicators-Chagi (OSTPI-C). The validation and reliability processes were carried out by 19 expert judges, who were required to meet at least four out of the five selected inclusion criteria. (2) Methods: The content validity was calculated using Aiken’s V coefficient value on qualitative (relevance, univocity, and importance) and quantitative levels (rating scale from one to five), through the agreement and consensus of the panel experts. The reliability of the instrument was analyzed using Cronbach’s alpha coefficient. (3) Results: The results demonstrated the high content validity indexes (0.90) and high reliability (alpha > 0.70) of the observational instrument. (4) Conclusions: The OSTIP-C observational instrument could be used in the Olympic and Paralympic Taekwondo sport environment as a valid and reliable tool to evaluate the technical execution of kick technical processes.

Análisis de las técnicas efectivas en Taekwondo: Revisión sistemática exploratoria (Effective techniques analysis in taekwondo: A systematic review)

“…Depending on the type of design used, there is a great variety among identified, such as instrumental studies (Yao, 2023;Sousa et al 2022), descriptive studies (Sant'Ana et al, 2014), quasi-experimental studies (Bešlija et al, 2017;Bakonska-Pacon et al, 2017), experimental studies (Ortenburger et al, 2016) using a cross-sectional approach (Seo et al, 2019). Analyzing a subject from different typologies of study and methodological approaches will allow us to know to a large extent all the factors that influence the performance of athletes from different points of view and analysis, drawing relevant conclusions.…”

“…Taekwondo is a full-contact combat sport where the most successful techniques are powerful kicks, which are delivered by hitting the opponent's chest gear or head (Norjali Wazir et al, 2019;Liu et al, 2021). This martial art and combat sport originated in medieval or similar cultures, and today it is primarily a combat activity conditioned by safety rules (Sousa et al, 2022). This sport aims to develop self-defense through combat (Wasik & Shan, 2015).…”

La Validación de dos programas de intervención para el aprendizaje del deporte alternativo “la Rosquilla”

“…El procedimiento utilizado se dirige hacia la recopilación de la valoración de los jueces expertos en torno a la adecuación y elaboración de las tareas (ítems) de los dos programas de intervención. Este método es usual en trabajos enfocados al desarrollo de instrumentos como cuestionarios para el análisis de la formación en voleibol (Collet et al, 2018), para establecer las preferencias y satisfacciones en jóvenes jugadores de baloncesto (Ortega et al, 2008), para valorar acciones tácticas en Rugby (Villarejo et al, 2014), para la medición de indicadores del rendimiento o evaluación del aprendizaje (Ibáñez et al, 2019;García-Ceberino et al, 2020b;Sousa et al, 2022). De manera más específica, concurren algunas validaciones orientadas a programas de intervención para la enseñanza de deportes de invasión en el contexto escolar (García-Ceberino et al, 2020a;González-Espinosa et al, 2017b).…”

Sport Performance Indicators of the Miluh-Chagi Taekwondo Kick Technical System

“…Taekwondo is a Korean martial art and combat sport, that has been an Olympic discipline since the Sidney (2000) Olympic Games, where kicking skills are crucial for a high motor performance. This combat sport originated in medieval or similar cultures, and today it is primarily a combat activity conditioned by safety rules [1]. Miluh-chagi is a Taekwondo kicking technique, and can be directed at the opponent's middle and higher zone.…”

“…The aim of this study was to analyze the athletes' technical indicators during the technical skill implementation of "a cycle of ten kicks" performing one Taekwondo technique namely -Miluh-chagi. This study used a previously designed, validated and published observation tool, the Observation System for Technical Performance Indicators -Chagi (OSTIP-C) Sousa et al [1].…”
